To provide a sealant film which has low-temperature heat sealability and easy peelability and is provided with sufficient shielding properties even when white printing or the formation of a foamed resin layer is not carried out, and also to provide a packaging material having the sealant film, a lid material made of the packaging material, and a container having the lid material.
In the sealant film 10, a shielding layer 12 containing specified high density polyethylene (b-1) as a main component and a specified amount of titanium dioxide (b-2) is laminated on one side of a seal layer 11 containing specified amounts of linear low density polyethylene (a-1) produced by a metallocene catalyst or a single site catalyst and at least one resin (a-2) selected from the group consisting of an ethylene-propylene copolymer, ethylene-butene copolymer, propylene-butene copolymer, ethylene-propylene-butene copolymer, and polybutene-1.
